Abstract

Treatment room for a patient for particle radiation-free caries diagnostics based on electromagnetic radiation with a wavelength above 300 nm in the dental field using an imaging method that does not require high-energy radiation, in particular for treatments using the so-called near-infrared technology

Description

The invention relates to a treatment room for a patient, in particular in the dental field for the application of a radiation-free imaging method, especially of the so-called near-infrared technique. The invention serves to optimally adapt the treatment environment to the requirements of the method.

This is achieved in particular by the implementation of a special lighting concept and the positioning of the relevant parameters, in particular of users, treatment devices and patients to each other. By adapting the treatment environment, a valid diagnosis for early detection and optimal utilization of the state of the art are made possible.

State of the diagnostic technique

So far, the state of the art for the detection of caries was essentially determined by X-ray diagnostics.

When passing through the body, X-rays transmit energy that is released to the tissue, which can alter or even damage biological structures directly or through subsequent processes. The human body has very powerful protective mechanisms that can repair most of these changes. A problem can arise when a higher radiation dose overwhelms the self-repair, or when individual unrepaired changes by chance degenerate (cancer develops) or damage the genetic material.

For these reasons, the patient is increasingly skeptical about X-rays.

In addition, early lesions can not be diagnosed with conventional methods at all, which is especially true for approximal caries.

A visual diagnosis of the dentist has the disadvantage that the caries typically occurring just below the point of contact of two teeth can be recognized only very late.

In order to avoid the largely subjective visual diagnosis of the dentist, non-imaging and imaging methods are known, but have numerous disadvantages.

Disadvantage of the non-imaging methods is essentially the poor interpretability by the dentist due to lack of information regarding the spatial arrangements.

The known imaging method for caries detection has in common that a wide-ranging illumination source is used, which illuminates the tooth completely or at least a larger part of the tooth or, if necessary. Several teeth simultaneously, creating inaccuracies.

Problem in diagnostics, it was now a method to develop that recorded with high accuracy changes to at least one tooth, especially caries in Approximalraum and that achieves a high image quality, which allows a diagnosis that largely corresponds to that which can be achieved with X-rays Without the disadvantages of X-radiation itself must be taken into account.

The prior art is that this problem according to the invention by the patent DE 10 2007 046 228.1 was solved in which by means of light in the near-infrared range using a camera, the tooth is used as a light guide. Carious lesions that block the light appear as dark-colored areas over the residual tooth substance in this application; a camera integrated into the treatment unit records the situation and transmits it to a computer screen in real time. The procedure is less stressful for the patient, and the procedure takes no longer than three to five minutes. "

The application of this technique is designed so that the treatment is carried out by means of a mobile device integrated into the treatment units in the normal treatment room. No defined treatment environment is used.

Problem with application of the technique

The present invention is based on the problem that the user of the art in the treatment environment of a normal treatment room is exposed to numerous imponderables, which preclude an optimal application of the technique.

According to Directive ASR 7/3 such as DIN 67505 In normal treatment rooms, an illuminance of at least 500 LUX for general lighting is prescribed. 1000 LUX must prevail in the area of the treatment chair and 5000 LUX are prescribed in the oral cavity of the patient.

Ceiling lights of conventional design rarely achieve the required illuminance. If But, often, even with special bulbs due to the large number of lights always a strong direct glare.

Due to the large number of different natural (windows / doors etc.) such as artificial light sources and mirror surfaces, direct and indirect glare and shadowing is the most common cause of lighting-related inaccuracies in the application of the technology in the normal treatment room. Light that is directly incident from a light source directly or through glossy, reflective surfaces almost inevitably prevents a consistent and valid diagnosis. This effect can be in the normal treatment room regularly but not turn off.

In addition, the necessary ergonomic arrangement of the treatment units, the doctor and patient monitors as well as the regular positioning of the patient and doctor / user in the "normal" treatment room does not meet the requirements, which requires an error-free application of near-infrared technology, because a variety of other treatments must be made possible ,

The use of the technology by the user is therefore subject to a high error rate.

The object of the invention is to provide a treatment environment which eliminates these sources of error and enables a valid diagnosis.

State of the art treatment environment

Previously known in the field of treatment environment is from the application EP 1785161 a treatment environment for particle therapy or particle therapy. This is a procedure of radiotherapy in the context of a cancer treatment. The method is used in particular in patients in whom conventional X-ray irradiation can not be sufficiently utilized because the tumor is either too deep in the body or surrounded by sensitive organs.

Troubleshooting

The present problem is in demarcation and improvement to the prior art DE 10 2007 046 228.1 achieved in that the application of the technique / treatment is outsourced to the treatment room according to the invention.

In contrast to the previously known treatment environment from the application EP 1785161 Electromagnetic waves having a wavelength of 1 mm and 300 nm (1 mm = 1,000 μm = 1,000,000 nm) are used in the treatment environment according to the invention. Preferably, beams between 300 and 1600 nm are used. In the treatment environment of the prior art applications (002,012), particle beams (protons, ions) or electromagnetic beams having wavelengths well below the range of 300 nm are used (X-rays, gamma rays).

According to the invention, a treatment room with a uniform light color is created, which has a uniform, soft and, above all, low-shadow illumination of the room.

This is achieved by the use of an opal-diffused light surface made of stretched film, the film being backlit with light-emitting diodes (so-called LEDs). The brightness is controlled by a dimmer integrated in the treatment unit. LEDs can be dimmed to 0% unlike conventional fluorescent tubes. Fluorescent tubes can only dim to 1%. An example of a suitable lighting concept is z. For example, the use of SMD stripes in aluminum cooling profiles, 24 V at 14.4 W / m output, light color 2700 K warm white, luminous flux 900 lm / m. Other products with comparable data can also be used.

In a typical and advantageous embodiment of the invention 5.0 m LED strips are totally installed in different segment lengths, with a total of connected load 72 W, total luminous flux 4500 lm. The lighting system is operated by a dimming actuator, which has a dimming range of 0.1-100% and is equipped with a 1-10 V interface for operation from the outside.

The benefit of these luminaires for color assessment lies in the high color contrast and the possibility of simulating different light situations. In addition, an optimal brightness distribution is achieved by a balanced distribution of the luminance, ie the visually perceived brightness impressions of illuminated areas in the room.

Unlike when used in a "normal" treatment room itself, the lamp adjusts, in such a way that at high illuminance, however, no direct glare from the lamp.

Furthermore, according to the invention, the brightness on the secondary work surfaces is limited to at most one third in comparison to the brightness of the work area. This avoids the deterioration of visual performance in horizontal and vertical surfaces.

In addition, wall surfaces with low luminances serve as rest areas for the eyes when looking up from work.

The treatment room is also characterized in that the orientation of the treatment unit / couch and the monitors is exactly adapted to the requirements of the diagnostic technique.

The patient monitor according to the invention is arranged at an angle of 22 ° -26 ° to the axis of the couch. This corresponds to the rotation of the patient's head during the diagnosis. Due to the non-parallel arrangement of the monitors of doctor and patient also reflections of the other monitor are avoided.

According to the invention, a 37-inch patient monitor is used, the center of which is at a height of 1.60 m.

Commercial use

The treatment room according to the invention can be marketed in cooperation with the inventor of the technique together or even isolated to a third party by licensing them or using comparable techniques. In addition, the results obtained can be used to cooperate with pharmaceutical companies, health insurance companies, etc., which can ultimately lead to a general improvement in prophylaxis and overall dental health.
